Rebuilt clock question
Just had the factory clocks cleaned up and made to work again in the Chevelle and the 409 (stock movement, not quartz).
How accurate are these things supposed to be? Clock guy says it can gain or lose 5 minutes a week and be within "spec". How are they fine tuned if out of "spec" other than adjusting via the normal stem adjustment?
What's everyone think or know about this?
Thanks in advance.
